AWS EC2 私有实例数据库连接
[英]AWS EC2 Private Instance DB Connection
问题描述
I have a VPC with public & private subnets (Windows 2019).
我有一个带有公有和私有子网的 VPC（Windows 2019）。 I installed Postgres database (not RDS) manually in the private instance.我在私有实例中手动安装了 Postgres 数据库（不是 RDS）。 As recommended by AWS I have created all the security group rules in public & private instance security groups.按照 AWS 的建议，我在公共和私有实例安全组中创建了所有安全组规则。 I wasn't able to connect to the DB from public instance.我无法从公共实例连接到数据库。 Please advise.请指教。 Thanks.谢谢。
Public instance security group:公共实例安全组：
- HTTP TCP 80 0.0.0.0/0 - HTTP TCP 80 0.0.0.0/0 -
- PostgreSQL TCP 5432 0.0.0.0/0 PostgreSQL TCP 5432 0.0.0.0/0
- RDP TCP 3389 0.0.0.0/0 - RDP TCP 3389 0.0.0.0/0 -
- HTTPS TCP 443 0.0.0.0/0 HTTPS TCP 443 0.0.0.0/0
Outbound:出站：

Based on the comments.根据评论。
The connection issue was caused by build-in firewall on Windows instances.连接问题是由 Windows 实例上的内置防火墙引起的。
The solution was to add rule to the firewall enabling port 5432.解决方案是将规则添加到启用端口 5432 的防火墙。
